UNITED STATES PATENT OFFICE.

W'ILLIAM A. LILLIENDAHL, OF JERSEY CITY, NEW JERSEY.

SUPPORT FOR SPECIFICATION forming part of Letters Application filed January 25, 1886.

To all whom it may concern.-

Be it known that I, WILLIAM A. LILLIEN- DAHL, of Jersey City, in the county of Hudson and State of New Jersey, have invented an Improvement in Supports for Steam-Pipes, of which the following is a specification.

The object of this invention is to protect the wood-work of buildings from the heat of steam-pipes. It has been found that Where woodwork is continuously exposed to the aetion of heat-such as in ordinary steam-heating apparatus,where the temperature ranges from 212o to Z500-the Wood-work becomes charred to such an extent that it will ignite vunder favorable atmospheric conditions.

My present invention relates to an improvement in the fastenings and supports for steampipes, in which I use a sectional ring of slate, soapstonc, or similar material of inferior conductivity between the steam-pipe and themetallic sectional ring that is attached to the woodwork, thus allowing the parts to be put around the pipe after it isin plaee,and lessenat the same time avoiding the objectionable noise that is often made by the steam-pipes as they slide upon the metallic supports in consequence of the expansion or contraction due to changes of temperature.

In the drawings, Figure l is a vertical section representing the improved supports as applied to a vertical steam-pipe. Fig. 2 is a plan of the floor-support, and Fig. 3 is a plan of the ceiling-support.

The metallic stock A is in the form of a divided ring, to which is applied the divided support B, made of soapstone, slate, or similar material. Vith a stock that is adapted to the ceiling of a building, the ring or flange l will be screwed to the ceiling, and the support B, of soapstone or similar material, is retained within the semicircular flanges 2 2. By plac- STEAM-Pipes.

Patent N0. 361,767, dated April 26, 1887.

Serial No. 189,585. (No model.)

In the stock that is adapted to the floor, I

prefer to make use of pendent fingers 4, to

pass down beneath and support the sectional or half rings B, of slate or similar material.

I do not claim a single rigid block of stone or inferior conducting material, with a hole through the same for the passage of a stovepipe; neither do I claim metallic supports for the same; and I am aware that a packing of asbestus, mineral wool, or similar material has been placed around a steam-pipe and within a tube or socket. These devices are not adapted to use under the circumstances where my improvements are available, because the steam-pipes require to be led in the proper direction, and. then non conducting material in separate pieces or sections introduced bep tween the metallic support and the pipe itself,

so thatthe pipe is free to expand and contract, and the pipe itself does not come directly into contact with the metallic support.

I claim as my invention- The sectional anged metallic support for steam-pipes,reeessed around the pipe and provided with openings for the attaching-screws, in combination with soapstone or other noncondueting material in sections Within the recess and separating the steanrpipes from the metallic support, substantially as specified.

Signed by me this 18th day of January, A. D. 1886.
